From a3db64c575ca201c9783f100c70b82d52bd78a93 Mon Sep 17 00:00:00 2001 From: "Jiri Slaby (SUSE)" Date: Mon, 27 Nov 2023 13:37:09 +0100 Subject: [PATCH] tty: make tty const in tty_get_baud_rate() MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit After commit 87888fb9ac0c ("tty: Remove baudrate dead code & make ktermios params const"), the 'tty' parameter is only read in tty_get_baud_rate(). Therefore, we can make 'tty' accepted in the function 'const' for clarity. The "the terminal bit flags may be updated." part of the tty_get_baud_rate()'s kernel-doc is dropped as it is no longer true. Because of the same commit above. And it was misplaced anyway.
